Valves

Diaphragm Valves

GF Harvel LXT® diaphragm valves are engineered to provide accurate throttling control and shut-off, utilizing a positive-stop, non-rising stem. The Weir-type design incorporates a PTFE diaphragm for maintaining purity, and uses EPDM o-ring seals on the union connections. Low-profile True Union design minimizes space while allowing for ease of installation and maintenance. Valves are supplied with both socket and threaded-end connectors for versatility. They incorporate a built-in position indicator, and are operated with a high-impact, hand-wheel-style handle for easy operation.

GF Harvel LXT® diaphragm valves are available in sizes 1/2" through 2" and carry a maximum pressure rating of 150 psi, non-shock @ 73°F.

Ball Valves

GF Harvel LXT® quarter-turn true union ball valves incorporate the same high degree of unique engineering design characteristics. Among these characteristics are heavy-bodied construction with strong buttress threads, full Schedule 80 bore to minimize pressure drop, PTFE floating seat design to minimize seat wear, EPDM or Viton^® o-ring seals, Safe-T-Shear^® stem, socket and threaded-end connectors, and True Union design for ease of installation and maintenance.

GF Harvel LXT® ball valves are available in sizes 1/2" through 4". 1/2" through 2" T.U. ball valves carry a maximum pressure rating of 235 psi, non-shock @ 73°F. 3" and 4" carry a maximum pressure rating of 150 psi, non-shock at 73°F.

1: Torque required at valve maximum internal pressure rating, 5ft/sec. Flow velocity; due to adjustment differences during installation, actual values may vary.

2: Gallons per minute at 1 psi pressure drop. Values calculated from laying length, based on derivative of Hazen-Williams equation with surface roughness factor C=150. Cv values are for basic Ball Valve only, excluding Tee connection.
